Application led June 23, 19217. Serie! No. 200,788.A I 'A My invention relatesvto lloose leaf* bindersind more particularly 1t yrelates to an iinvi e an improved binder-locking mecha.-

nism wliichinay be expeditiously actuated .by a simple movement to quickly release the .locking mechanism to enable `leaves to be inserted intoA the binder or to be with-V drawn therefrom. 1 i

Another objectof my invention resides inl` n jerablyiremovable by withdrawing screws 4 the provision of an improved loc'ljing.- mechanism for loose leaf binders which isduryable inv construction, positive in operation,

and which may be economically produced expensive parts comprisingthe same.

These and other objects of my yinvention and theinvention itself will become apparent from reference to the following' description of an embodiment thereof and in which descriptionl reference will be had to the an specilication.

' Fig. 3 isa sectional yview of the embodiment taken on the line of "Referring to all the iigures kof the draw ings, in all of which like parts are desig'- nated by like reference f ycharacters,l and wherein l have illustrated an embodiment of my invention7 preferably comprising 'a' housing` or casing 10 formedfof' light weight metalliematerial such as aluminum or thelike and having heavyy fabric lll, such as bnckram' or the like rivetedto .a side wall atfS and extending,vr about afbinden cover. body lflormed ofc'ardboard' or theY like materiaL The lf'ab'ri'c may be riveted together Vatv7 to strengthen. the same and vprovides a. hinge connectionat 17 between the casingaiid binder cover. A paddingk orfthe like may be disposed of the covers.Y At I showV on the 'outside or housing fl foregoing aA lower binder section 'on adapted to support ar pair of binder posts l5 and 16' extending upwardly therefrom and projected towards the metallic casing O. The plate 1.4 is also covered with .a heavy fabric 5 :which also provides a. hinge connection 'between this plate and'a second binder cover, not shownybut substan'# y tially the sanieas the cover 12.*'

The topy and bottom walls 19 and 2() of the casing 10 are provided with a pair of aligned aperturesadjac'ent the ends thereof` through whichl the: posts laiid 16 maybe projected and disposed with a portion with in the 'housing 10.y The l top wall "l9'is pref to permitl access 'to' the interior kof the' casing 10 and to facilitate assembly of thelocking mechanism for thev'binder which will hereinafter be described in detail. A pair ol?l bearing brackets 2l and 22' are ,disposed inl the casing l() depending from the 'inner side of the removabletop 'wally thereof and providing supporting bearings upon which a horizontally disposed rod' Qllis journaled Within the casing with .its ends disposed adjacent to the binderk posts. ,Axially extend;

ing `hollow threaded bores 25" andv 26 are f The threaded connection between the rojd f and jawmembers are right and left-hand threads,respectively, and thus rotation of the rod inits bearings in one di-'re'ctiori'willr cause the jaw members toy be Inovedrelatively towards each other oraway from each other depending upon the' direct-ion lof rotation of the rod, inamanner similar-toa turnbuckle, both as to-thefcon'struction and opration thereof. The'threaded connection beingjcapable of giving but a relatively short'movementof thejaw members axially necessaryf'that the rod 24be'rotateda few turns to effec'tthe desired`moveinent of the ljaw members to engage or disengag'e vthem 'with the binder posts loeand I16.r The rod 24 105 Y in either and*oppositedirectionsyit is only is preferably formed of a plurality of joined sections. fr rotatable knob or operating handle 36 is slidably mounted on the intermedia-te non-circular portion 63 of the rod is provided with a non-circular bore 37 into which the intermediate portion 63 is disposed and thus the rod and knob are'` non-rotatable relative to each other, but, at the same time, permit the knob to be slid axially on the rod for a purpose whicliwill hereinafter be set forth. the knob is roughened or knurled to facilitatethe rotating of the same by tue li or thumb of a of the binder, les nY the possibility of slippage. VThe ends of the portion 63 of the rod are recessed and are adapted to receive a reduced ended of the outer'rod sections and G6, the three sec tions being joined together by virtue of transverse pins 67.

An opening 39 is provided in the top wall of the casing intermediate the ends thereof through which the knob periphery extends and projects above the top wall outer face and thus a user may rotate 'the knob by` engaging a finger with the knurled periph@ ery thereof and thereby move the jaw meinbers relative to each other. Small recesses 40 are formed in the side il of the knob and arranged in a circular formation around the center thereof, and are adapted to receive a pin 42 carried by the top wall of the casing and projecting into the opening 39. When the knob is slid to the left, the pin telescopes into one of the recesses d0 and thus locks the knob against accidental movement.

When for any reason itis desired to insert or remove binder leaves from the binder, a user ofthe afore-described binder ma7 by a simple operation shift the knob to the right by a finger r-or thumb engaging with `the same, and then by rotating the same in the direction of the arrow 50, Fig. l, cause the jaw members to be moved towards each other, disengaging the jaw members from contact 'with the posts l5 and 16, and thus the binder cover l2 may be withdrawn from the posts l5 and 16, enabling binder leaves to be inserted therein or permitting with'- drawal of the binder` leaves therefrom. By virtue of the limited number of threads on thejaw members at 27 and 28, movement of the jaw members towards each other is but a limited one, and thus it is not possible for them to engage the posts l5 and 16 by rotating `the rod 24 in the direction of the arrow 50.

In order to cause the jaw members to grip the binder posts after leavesv have been inserted `in the binder and the casing has been placed `over the binder posts and to prevent accidental relative movement of the cover, the knob may be rotated in the direction opposite to that of the arrow 51 which n vervr looped 'the portion 60 and 6l of the ring portions of the jaw members are contacted with the posts and lock the binder covers onto the posts-l5 and 16. l

rlhe hinge connection between the binder covers and the casing l0 and stationary sec-V tion 13 will enable the binder covers to be opened closed in normal use of the binder.

All of the parts described binder locking mechanism may be vmade of a metallic material of light weight and of small size and thus render the 'same easy to handle without sacrificing sturdiness construction and durabilityvin use. rllhe parts are so associated and assembled that they may be readily replaced when worn by new parts and thus economy in upkeep is accomplished. From the foregoing it will be apparent that l may produce arbinder thel loose leaf type which is of inexpensive and of simple construction and very 'emcient and convenient in use and which may be quickly operated with a minimum efl'ort.

Having thus described my invention in a specific embodiment7 l am aware that numerous and extensive departures may be made from the embodiment herein illustrated and described without departing from the spirit of my invention.
